VALVE.

Specification of Letters Patent.

Patented Feb. 17, 1920.

Application filed .Tune 19, 1919. Serial No. 305,415.

To all whom 2'?? 'may concern Re it known that l, STAN'ISLAW Konxosz, a citizen of Russia, residing at Rotterdam, in the county of Schenectady and State of New York, have invented certain new and useful improvements in Valves; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. Y

This invention relates to valves, and more specifically to an improved faucet-valve structure.

One object of this invention is to provide an improved valve structure in which the wearing parts can be removed and replaced by new ones when necessary, and in vwhich the ordinary non-metallic packings are dispensed with, metallic packing rings being provided in a' novel combination and arrangement.

Other objects and advantages may become apparent to persons who read the following details of description in connection with the accompanying drawings in which:

Figure 1 is a longitudinal vertical sectional view of my improved faucet valve.

Fig. 2 is an elevation disclosing one of the members of the valve in detail.

Fig. 3 is a central vertical sectional view vof the member shown in Fig. 2.

Fig. 4 is a horizontal sectional view, the section being taken along the line 4-4 of Fi 3.

Fig. 5 is an elevation of my improved valve stem.

Fig. 6 is a perspective view of one of the metallic packing rings which are carried by the valve stem.

Referring to the drawings in detail, in which similar reference characters correspond with similar parts throughout the several views, my improved valve comprises a faucet body 7 formed with an upward tubular extension 8 having a cylindrical bore 9 therein. The member 7 is formed with a Huid passage 10 having a valve seat 11 which is in axial alinement with the bore 9. A ball 12 of metal, glass, or other appropriate material constitutes the valve-closing `member, and the same is movable toward the valve-seat by means of a valve-stem 13. The members 12 and 13 are preferably separate from one another, but are so closely related Ythat they combine to form the valve-closing means, as will hereinafter become more apparent. The valve-stem 13 has its inner end provided with screw threads 14 which mesh with screw threads 15 of a sleeve 16 which is removably applied in the bore 9 and is provided with a peripheral flange 17 at its outer end, this flange being closely fitted on thev outer end of the tubular element 8, or about the outer margin of the bore 9. A cap 18 has threaded engagement with the outer end of the tubular element 8, and when this cap is screwed down tightly, the joint between the Harige 17 and tubular element 8 is fluid-tight. However, by removing the cap 18 thc sleeve 16 may be easily removed from the bore 9, and another sleeve or bushing 16 may be substituted for one which has become worn by long usage.

The valve stem 13 is formed with one or more annular grooves or packing seats 19 between its threaded inner end and its outer end, and a packing ring or rings 20, suchl as shown in Fig. 6, or of any appropriate construction, may be fitted in the grooves 19 and constitute a packing between the adjoining surfaces of the valve stem 13 and sleeve 16. These packing rings are preferably of such springy material that they may be expanded when placing them in their respective seats, and may be compressed when placing them within the sleeve 16, and they continually exert an outward pressure against the sleeve 16 so as to eifectually prevent leakage between the members 13 and 16. The relation of the screw threads 14 and 15 is such that they limit the outward or unscrewing movement of the valve stem, and the sleeve 16 is extended outward beyond the packings 20 when the valve stem has been unscrewed to its fullest extent, and therefore, the packing rings cannot become displaced during the working operation of the valve.

The sleeve 16 may be formed with depending arms 21 which constitute a cage for the valve member 12, and the screw threads 15 extend into these arms 21, so that this improved valve structure may be thoroughly effective without the necessity of unduly extending the tubular element 8 farther outward.

Any appropriate form of wheel or handle 22 may be employed for turning the valve stem, and any appropriate means may be employed for securing the valve structure or faucet to a liquid container, screw threads 23 being indicated for this purpose.

Although I have described this embodi- -Cri ment of my invention very specifically, it is not intended to limit this invention to these exact detailsof'construction and ar rangement, but changes may be made Within the scope of the inventive ideas as implied and claimed.

' Vhat I claim as my invention is:

1. A valve comprising a body formed with a {luid-passage, a valve-seat and a cylindrical Abore communicating With said passage at said valve-seat, an internally threaded sleeve having a cylindrical outery surface fitted removably in saidcylindrical bore and having a flange fitted on theV outer margin of 'said bore, a cap fitted on saidbody and being,

eli'ective to hold said flange on said margin sonas to make a vHuid-tight joint between said bod-y and Hang@ the internal threads of said sleeve terminating between the inner and outer ends of said sleeve, an externally threaded valve-stem-Whose threaded portionl meshes with the screw threads of said sleeve and is therebyT limited `in its Vunscrevving Y movement, a separate valve-closing member ymovable by said valve-stem to its closing position, and a packing carried by said valve-stem, said sleeve being extended outward beyond its threaded portionsuiciently to iiiclose said `packing when said valvestem is unscreWed to its fullest extent.

2. A valve comprising a valve-seat,. a valve-closing member seatable on said-valveseat, a cage comprising a plurality of spaced serrated bars arrangedaround said valveclosing-member, .a valve-stein having threads at its inner end meshing with the serrations of said bars and being` operatable to seat said valve-closing 1 member.

In testimony whereof I have hereunto set my hand. 4
